Application filed October 12, 1907. Serial No. 397,040.

To all whom it ma/y concern:

Be it known that I, GILroRD S. MURDooK,

and State of Michigan, having invented certain new and usefulImprovements in Brush- Making Machines, of which the following is aspecification, reference being had therein I to the accompanyingdrawings.

This invention relates to improvements in I brush making machines ofthat class in which the fibrous material is automatically fed in bunchesto stapling mechanism which also embodies means for making and drivingthe staples; and the objectof the invention is to provide a feedingmechanism which will gather from a suitable hopper a bunch of materialof the desired size, and firmly hold the fibers straight and even as itfeeds the bunch to the stapling mechanism.

A further object is to provide a hopper so constructed and arranged thatthe fibrous material is firmly held straight and even therein and fed tothe delivery slide in such a manner as to insure the delivery of a fulleven bunch each time, and also to provide a machine embodying certainother new and useful features in its construction, combination andarrangement of parts, all as hereinafter more fully described referencebeing had to the accompanying drawing, in which Figure 1 is a plan viewof a device embodying the invention, with parts broken away to show theconstruction; Fig. 2 a vertical section of the same substantially on theline .r:u of Fig. 1; Fig. 3 is an enlarged detail showing a front.elevation of the hopper, stapling, and feeding mechanisms; Figs. 4 and 5are similar details showing the operation of the bunch releasing lever;Fig. 6

is an enlarged detail showing the closing g plate of the feed slide andthe adjustable stop therefor with the adjacent parts of the machine:Fig. 7 is an enlarged detail showing the hopperin end elevation with itspresser, foot and mechanism for operating the same; Fig. 8 is alongitudinal section of the hopper on the line g y of Fig. 7 Fig. 9 is aperspective view of one of the adjustable hopper partitions detached;Fig. 10 is a. perspective view of the feed slide and its supportingguide;

residing-at Detroit, in the county of lVayne j mounted at its rear edgea shaft 2 provided at one end with a driving pulley 3 which is 1 is asuitable bed or table upon which is loose on the shaft and is attachedthereto to turn the same, by a suitable clutch 4.

5 is a bracket secured to the table 1 at its forward edge and providedwith vertical guide ways for the reciprocating slide or head 6 which isactuated by a rocking lever 7 pivoted intermediate its ends with itsforward end projecting between friction rolls 8 on the slide and itsrear end engaging a cam wheel 9 on the shaft 2 for actuating the slidein both directions.

10 is a vertically movable die block traveling 1n guides 11 secured tothe table directly below the slide 6 and 12 in a lever engaging saidblock to operate the same, which lever is pivoted intermediate its endsand at its rear end engages a slotted or grooved cam 13 on the shaft 2for operating said lever in timed relation to the movement of the slide6 which slide has secured thereto a needle 14 working vertically throughthe die block in a suitable passage provided therefor having grooves toreceive the ribs 15 on the needle. said grooved passage forms a die toreceive a wire which 1s formed, upon the downward movement of the block,over the end of a finger bar 16, into a staple. This finger is projectedinto the path of the die and retracted therefrom in timed relation tothe movement of the other parts by being piv otally attached at its rearend to a rocker 17 pivoted intermediate its ends on the table andattached at its opposite end to the forward end of a reciprocating rod18 which is moved by an internal slotted or grooved cam 19 on the shaft2. Carried by the die block is a suitable knife 20 for severing the wirein proper lengths for the staples and the wire is fed in by'suitablelevers 21 pivoted on the table and actuated by a cam 22 on the shaft 2,the forward end of the forward lever being provided with a suitablegripping device 23 to engage the wire and a similar gripper 24 beingprovided to prevent the retrograde movement of the wire.

All of the foregoing described parts are cross-section of the same; andFig. 12 is a 5 arranged and constructed to operate $1110- The lower endof stantially as shown and described in my application for LettersPatent filed in the linited States Patent Ofiice on 2nd day of August1907, Serial No. 386.722.

it long feed hopper for holding bristles or fibrous material, is securedin an inclined position to the supporting frame or table of the machine,with its lower or discharge end adjacentto the guide bracket 5. Theupper side of this hopper at its lower end is open and through thisopening 26 is fed the material which is placed in the hop- 5 per throughan opening in its upper side the discharge opening.

and at' theirrear ends are provided with shoulders 29 to engage notchesin the end of the hopper and at their forward ends, are formed withdownwardly extending shoulders 30 at the lower edges to engage aextending ears on the hopper and hangs downward through a slot thereinto engage the lug and when the slide is drawn out. the latch will swing,permitting the lug to pass, but. when the slide moves inward the end ofthe latch engages said lug and being prevented from swinging in theopposite direction by engagement with the end of its slot, it preventsthe inward movement of the slide until turned out of the path of the lugby the operator. j

The lower end of the hopper is rounded at its lower side so that it willtake up less space adjacent to the stapling mechanism and also guide thematerial upward toward is left open and provided with strips or lingers43 extending across the open end and secured at their upper ends to thehopper at: the upper edge of the open end (see Fig. 7) to prevent. thematerial from escaping, and between these strips is a presser foot.v 44of any suitable form which engages the lower side of the bunch ofmaterial and presses bar 31 extending across the lower side of the ihopper, which bar is strongly pressed and held in engagement with theshoulders by springs so that each partition is forced longitudinally bythe springs to yieldingly hold its shoulders 29 in engagement with theirnotches. Adjusting screws 33 side of the hopper near its lower end intoengagement with the partitions and thus said partitions are firmly heldin place, and at the same time may be quickly and easily adjusted towardor from each other to accommodate the'ditl'erent lengths of material,

by turning the screws in or out and against I the action of the springs32, disengagmg the extend inward through each1 shoulders at the upperends of the partitions T from their notches in the casing and movingthem in or out into engagement with other notches. The partitions arealso provided with flanges i-B-l within the discharge opening 26 of thehopper, which flanges extend over the ends of the material a short disofthe lever 47 between its pivot and its hopper. said slide being actuatedby weights cud ot' the slide by cables running over pulleys on the sidesof the hopper. Friction rolls 39 in the bottom ol' the hopper casingengaging the slide,- insure l'rce movemcnt thereof, and on the inner endof said slide is a .lug ltl to engage a stop pm 41 in the top ot' thecasing and prevent the slide from being pulled entirely out when liftedto till the hopper. a gravity latch l2 being also provided adjacent .tothe stop pin to l|old the slide while the hopper-is being tilled. Thislatch is pivoted upon upwardly l l l l the same upward toward thedischarge opening. This foot is carried by a lever 45 extending beneaththe table 1 and pivoted intermediate its ends between ears 4.6 on asecond lever 47 which is provided with a friction roll .at one endengaging a cam 48 on the shaft 2 and at its opposite end with a coiledspring 49 interposed between it, and the lever 45. The second lever ispivoted intermediate its ends between ears 50 on a supporting bracketwhich is secured to any convenient part of the machine-frame beneath thetable and which is formed with laterally extending arms one of which isprovided with a guide lug 51 for the roll end of the lever 47 and theother arm with an adjustable stop screw 52 to engage the lower edge ofsaid lever near the end thereof carrying the spring 49. An adjustingscrew 53 is provided for said spring to regulate its tension and thelever 45 is adjusted relative to the lever +7 by a set screw 54 passingtherethrough and engaging the upper edge rear end carrying the cam roll.The lever l7 when turned on its ear pivot 50 is guided in; its movementby the lug 51 on the fixed braclt'et-arm and is limited in its turningin one direction by the stop-screw 52 on the ing to actuate the presserfoot in timedrelation to the movement of, the mechanism which feeds thematerial in bunches to the stapling mechanism and the spring-l9yieldmgly pressing the foot into contact with the This rounded endmaterial, thus putting an even pressure thereon regardless of thevarying density of the bunch of material in the hopper.

Suspended over the hopper in the central vcrtial plane thereof, bybracket arms secured to the table. is a guide 56 for the feed slide 57which slide consists of two relatively movable members or plates 58 and59, the member 58 being formed with laterally extending flanges 60 atits upper edge which are adapted to slide within the grooves formed inthe inner edges of the side bars (31 of the guide. Bolts or pins 62 aresecured to these bars and pass loosely through openings in the top plate63, and on these pins between their heads and the said top plate aresleeved coiled springs which exert a force to draw the bars toward saidplate and frictionally clamp the flanges of the slide between. Themember or plate of the slide is formed. with an extended portion orfinger til at one end having a deep notch or cut (35 in its lower edgeat a distance from its end, extending inward toward said end at anangle, a corresponding plate 99 having a finger 100 is secured theretoto form a hook to engage the material in the opening in the hopper andto form a pocket to receive the desired size of bunch, the size or depthof said notch or pocket being determined by a slide (36 adjustablysecured to the finger and having a tongue projecting into said notch.The closing plate 5!) is attached to one side of the member 58 by tapscrews 07 extending through slotted openings 8 and (it) in said plate,the forward opening (3t) being formed with a notch at one end so thatthe forward end of said plate is free to rise when the plate is movedrelatively to the member 58 with said screws in the forward ends oftheir slots. \Vhen the plate is moved forward relative to the member 58,its forward end lies beyond the point of the hook, thus closing theopening into the slot and firmly holding the bunch of material therein,and said end is also cut at an angle and provided with a groove 71 sothat. when the feed slide is at the forward end of its stroke, said endforms one side of a guide for the staple which in the operation of themachine has just been formed over the finger, the opposite side of theguide being formed by the grooved end of an adjustable plate 72.

To cause the closing plate 59 tostop in its forward movement in exactlythe desired position to receive and guide the staple, a stop plate 73 issecured to one side of the bracket forming the ways for the die block.and within a suitable undercut groove in the side of said bracket is atapered wedge 74 having an inclined edge to engage the undercut side ofthe groove. -An ear 7?) is provided on the outer end of the wedge and ascrew It; having a head to engage the can passes through a slot in saidear and engages a screwthreaded opening in the bracket. A shoul der 77on the closing plate engages the stop plate when the feed slide is inits forward position and by turning the screw 76 the wedge is forcedbeneath the stop plate to adjust the same, so that it will stop theclosing plate at the desired point.

To reciprocate the feed slide, a lever 78 is pivoted at one end on themachine table and its opposite or forward end fits into and pro jectsthrough an opening 79 in the closing plate 59 and on through a slot 80in the finger plate 58. A rocker bar 81, pivoted inter mediate its endson the table, is provided with a roll at its rear end to engage a camslot in a-cam wheel 82 on the cam shaft 2 and at its forward end isconnected by a link 83 to the lever 78. baid link is provided with ajoint 84: to permit of annular movementof the lever and with a socketmember 85 having an internally screw-threaded bore to receive ascrew-threaded eye bolt 86, the socket member being detachably pivotedtoan eye bolt 87 on the end of the rocker bar, so that it may bedetached from said bar and turned on its eye bolt to adjust the lengthof the link and thus change the throw of the lever. A further adjustmentis secured by providing a clamping socket 88 on the end of the rockerbar to receive a sleeve in which the end of the eye bolt 87 is free toturn, said sleeve may be moved in or out of said socket by loosening theclamping screw and the length of the rocker thus changed. \V hen thefeed slide is at the rear end of its movement, the first forwardmovement of the lever 78 moves the closing plate 59 without moving thefinger plate 58, said finger plate being frictionally held bytheclamping guide 56 and the elongated slot 80 in said plate providingsuch movement before the lever engages the end of the slot to move thefinger plate. This moving of the closing plate relative to the fingerplate, closes the hook which on the up movement of the slide has beenfilled with material and clamps the same therein, firmly holding thebunch as the slide is moved downward and forward to bring said bunchbeneath the needle. aml directly over the opening in the chute 89. Thelower end of the chute is above and adjacent to a suitable supportintable 90 adjustably secured in any desired manner to the machine frameand upon which table the brush block to be filled with tufts is placed.\Vhen the slide is stopped by the engagement of the shoulder 77 with thestop plate 73, the bunch lies bet ween the end of the closing plate ofthe slide and the end of the plate '72 in position to be embraced by thestaple as it is forced downward by the needle. 'lo release the bunchfrom the hook in timed relation to the movement: of the needle. thefinger plate of the feed slide is moved independently of the closingplate after the latter has engaged its stop, by a bar 91 having aninwardly extending lug 92 on its lower end to engage a roller stud 93 5on the side of said. finger plate. This releas- I ing bar is attached toone side of the vertically extending bracket forming the guide way forthe head 6, by tap screws passing through longitudinal slots 9-1 and 95in said bar, and on the side of said bar near its upper end is alaterally projecting lug 96 adapted to be engaged by an outwardlyprojecting stud 97 on the reciprocating head to raise the bar. A fingerplate 98 is also provided on the head to engage the upper end of the barand move the same downward as the head moves down. The stroke ormovement of thebar is much less than that of the head and therefore todisengage the finger plate from the end of the bar and permit the headto pass on, in its downward movement, the slots 94 and 95 are inclinedrelative to the vertical path of the head so that as the bar is moveddownward, it moves laterally away from the head. The lug 96 is of suchlength that it projects into the path of the stud 97 at all times and soupon the upstroke of the head, said stud engages beneath the lug andraises the bar.

The cam operating the feed slide, and the cam for the head are soconstructed and set that the movement of thehead relative to theslide-is such that the slide is moved into position to deliver the.bunch before the delivery bar moves down to engage its lug with the studon the finger plate and said slide is stationarily held in that positionwhile the bunch is being released. When the bar has moved downwardsufficiently to bring its lug opposite the stud, its lower end carryingsaid lug is swung laterally to move the finger plate, by providing anoflset or crook in the slot 94. Further downward movement of the barcarries its lug out of the path of the stud so that the feed slide maybe retracted to again pick up a bunch from the hopper, the closing plateof said slide being free to rise slightly at its forward end during suchmovement by reason of the notch 70 at the 50 end of the slot to give thematerial in the hopper free access to the hook. This construction offeed'slide insures the picking up of a full bunch each time and holdingthe same firmly'and evenly, and taking the material from the upper sideof the hopper, permits locating the hook at the'lower side of the slideso that when'said hook is opened the bunch is entirely free from saidslide and its entry into the forming opening isnot 0 hindered thereby.

102 isv a spring pressed bumper traveling in a guide 103 and adapted toreceive the shock of the head 6 on the return movement of the head and104 is a similar bumper. for

5 the lever 7.

lVithin a socket formed 011 the lower end of the hopper directly belowthe feed slide, is an adjustable pin 105 held therein by a set screw106. This pin is adjusted so that its upper end engages the lower edgeof the feed slide and as the slide moves forward carrying the bunch ofmaterial in its holding notch, the pin will catch or scrape away anyfibers that are not wholly embraced by the notch but are partially heldby the notch or bunch and carried forward thereby. The pin also forms arigid support for the slide.
